The decrease of natural energy reserves encourages researchers to search for alternative energy and more efficient equipment and machines. As an effort to contribute in distributing research outcomes, the Mechanical Engineering Department of Petra Christian University conducted national conferences in the past 12 years. To reach a broader audience, starting from 2018 the ME Department conducts an international conference, an event that is expected to allow local researchers to interact with their overseas fellows. In addition, this conference is designed to encourage local authors to publish their research works in reputable journals and proceedings.
